The Energy Structures of Titanium Carbide

Abstract

The spectra of titanium and carbon in the homogeneity range of titanium carbide (TiC0.54-1.0) were measured in small composition stages, under high resolution conditions. The carbide specimens were synthesized from high-purity raw materials under conditions conducive to the presence of a minimum amount of dissolved gases and free carbon in them. The combination of the K and L spectra of titanium, which are responsible for the p and d states of the metal, with the Kα band of carbon in the homogeneous carbides, which reflects mainly the 2p electron states of the carbon atom, enabled a number of considerations to be advanced in regard to the structure of the valence band of the carbide crystal and to the effect of carbon concentration on the energy spectrum.
